1. What is Huberplex and what is it used for

Huberplex is a medicine that contains chlordiazepoxide hydrochloride as the active substance. Chlordiazepoxide hydrochloride is a psychotropic substance that belongs to the group of medicines called benzodiazepines.

• For the short-term treatment (2-4 weeks) of anxiety, which may occur alone or in association with insomnia.
• To control muscle spasms (along with other medications).
• In the treatment of alcohol withdrawal.

You should consult a doctor if your symptoms worsen or do not improve.

2. What you need to know before taking Huberplex

Do not take Huberplex:

• if you are allergic to chlordiazepoxide hydrochloride, benzodiazepines, or any of the other ingredients of this medicine (listed in section 6).
• if you have breathing difficulties related or not to sleepfor a long time (sleep apnea).
• if you have a disease called "myasthenia gravis", which is characterized by muscle weakness and fatigue.
• if you have severe liver damage
• if you are breastfeeding

This medicine is not recommended for the primary treatment of psychotic disorders (severe mental disorders that cause abnormal ideas and perceptions), nor should it be used as the only treatment in patients with depression, alone or associated with anxiety. Your doctor will probably have prescribed another medicine for these cases.

If you have any doubts, consult your doctor.

Warnings and precautions

Consult your doctor or pharmacist before starting to take this medicine:

• if you have any liver or kidney problems
• if you notice any change in your personality, or reactions such as restlessness, agitation, irritability, aggression, confusion, outbursts of anger, nightmares, hallucinations, psychosis, and inappropriate behavior. If this happens, you should consult your doctor and stop treatment.
• if during treatment you suffer from recent memory losses (anterograde amnesia). To reduce this risk, take the medicine at bedtime to ensure you can sleep uninterrupted for 7-8 hours.
• after continuous use of this medicine, some loss of effect (tolerance) may be detected
• after stopping the medicine, especially if the medication is stopped abruptly, rebound symptoms and anxiety, mood changes, and restlessness may appear, so it is recommended to gradually reduce the dose before stopping treatment.
• if you suffer from drug or alcohol dependence, you should not take this medicine unless your doctor tells you to.
• lower doses are recommended in patients with chronic respiratory problems and in elderly people

Risk of dependence

The use of benzodiazepines can lead to dependence. This occurs mainly after continuous use of the medicine for a long time. To minimize the risk of dependence, the following precautions should be taken into account:

• the use of benzodiazepines will only be done under medical prescription (never because they have worked for other patients) and will never be recommended to other people.
• do not increase the prescribed doses in any way, nor prolong the treatment for longer than recommended.
• consult your doctor regularly so that he can decide if treatment should continue.

Children and adolescents

Huberplex should not be given to children unless it is strictly necessary. The duration of treatment should be as short as possible.

Taking Huberplex with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medicine.

This is extremely important because the simultaneous use of more than one medicine can increase or decrease its effect.

Therefore, you should not take other medicines at the same time as this medicine unless your doctor is informed and approves it beforehand. In particular, inform your doctor if you are taking any of the following medicines:

• Antidepressants, sleep-inducing medications, neuroleptics, hypnotics, tranquilizers.

(may increase muscle relaxation effects; greater risk of falls in elderly patients) or other medicines that act on the brain and

nerves

• Pain relievers or anesthetics.
• Antihistamines (used to treat allergies) that cause drowsiness (e.g., chlorphenamine)
• Medicines used to treat epilepsy (e.g., phenytoin and phenobarbital).
• Medicines that affect the liver (e.g., the antibiotic rifampicin and cimetidine,

omeprazole, macrolide antibiotics (erythromycin); medicines used to

treat stomach problems, disulfiram, and contraceptives).

• Medicines used to treat viral infections (e.g., ritonavir) since these medicines can enhance the action of benzodiazepines.
• Medicines used to treat high blood pressure (e.g., beta blockers, anticoagulants,

cardiac glycosides, moxonidine)

• Medicines known as dopaminergic (e.g., levodopa, for the treatment of Parkinson's disease).
• Sodium oxybate used in patients with narcolepsy. (possible increase in respiratory depression)
• Theophylline; medicine to facilitate breathing

The concomitant use of this medicine and opioids (strong painkillers, substitution therapy medications, and some cough medications) increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and can be life-threatening. Therefore, concomitant use should only be considered when other treatment options are not possible.

Tell your doctor about all opioid medications you are taking and follow the dosage recommendation carefully.

Taking Huberplex with alcohol

Avoid consuming alcohol during treatment. The effect of alcohol can enhance sedation, and this can affect your ability to drive or operate machinery. If you need more information on this, consult your doctor.

Pregnancy and breastfeeding

Consult your doctor or pharmacist before using any medicine.

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine. Your doctor will then decide whether or not to use this medicine.

Benzodiazepines are excreted in breast milk, so you should not take Huberplex during breastfeeding.

Driving and using machines

Huberplex can affect your ability to drive or operate machinery, as it can cause drowsiness, reduce your attention, or reduce your reaction time. The appearance of these effects is more likely at the start of treatment or when the dose is increased. Do not drive or use machines if you experience any of these effects.

Huberplex contains lactose, sucrose, wheat starch, and orange yellow S

This medicine contains lactose and sucrose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medicine.

This medicine contains very low levels of gluten (from wheat starch). It is considered "gluten-free" and is very unlikely to cause problems if you have celiac disease.

One tablet does not contain more than 0.1 micrograms of gluten.

If you have a wheat allergy (different from celiac disease), you should not take this medicine.

This medicine may cause allergic reactions because it contains the colorant Orange Yellow S (E-110). It can cause asthma, especially in patients allergic to acetylsalicylic acid.
